ADDITIONAL INFORMATION
It used to work without problems.  After a few updates the problem always occurs.

The computer boots right into 22.04, shows the lockscreen - it is set for Plasma(X11).  It shows the splash screen, and then goes into the desktop without problem.

I have purged the nvidia drivers and reinstalled them to no avail.  (535-server)

I'm afraid Plasma 5.24 is unfortunately no longer eligible for support or maintenance from KDE.

Plasma is a fast-moving project, and bugs in one version are often fixed in the next one. Please update to a later version of Ubuntu. Ideally Ubuntu 24.10 so you get a version of Plasma 6, but even 22.04 would be better, and give you Plasma 5.27. 

Thanks for understanding!
